The Bloom Mastery Billboard aka Bloom Mastery Sign Billboard was originally released on December 7th, 2012 for the storage of bloom mastery signs.
It can store bloom mastery signs the way storage buildings such as barns and sheds do, but unlike these which require a Barn Raising to increase the number of items they can store, the storage capacity is increased by collecting building materials, and when fully expanded it can hold up to ? items.
